50 Ohm Coax Cable Explained: What It Means, Why It Matters, and How to Choose
A 50 ohm coax cable is a transmission line with a characteristic impedance of 50 ohms, and it is the default choice in most RF systems because it balances low signal loss with reasonable power-handling capability. The “50 ohm” rating does not refer to a DC resistance you can measure with a multimeter; it describes ho...

Antenna Connector Types: SMA vs N Type vs TNC vs BNC vs RP-SMA Complete Guide
Choosing an antenna connector is one of those small decisions that can make or break an RF installation. Get it right, and the system performs almost invisibly; get it wrong, and you lose signal before power even reaches the antenna. For nearly every radio, Wi-Fi access point, cellular modem, or IoT gateway, the main...

Coaxial Cable Selection Guide: Choosing Cable, Connectors, and RF Performance
An RF engineer once told me that most field failures are not component failures; they are selection failures. Selecting a coaxial cable starts with three decisions: characteristic impedance, cable size, and connector family. Get these three right and the rest of the design has a predictable signal path. Get one wrong...
SSMC RF Coaxial Connectors Industry knowledge

SSMC RF Coaxial Connectors are sub-miniature, snap-on style interconnects used to terminate and join coaxial cables in high-frequency signal paths. Compared with threaded miniature series, SSMC RF Coaxial Connectors use a push-on/snap-on mating mechanism, which shortens assembly time in space-constrained, high-density board and module designs. This connector family typically operates at a nominal impedance of 50 ohms and covers a broad frequency range from DC up to 10 GHz, making it suitable for RF modules, test fixtures, telecommunication equipment, and instrumentation where compact footprint and repeatable electrical performance are required. As a supplier of RF interconnect components, Yangzhou Jingcheng Electronics Co., Ltd. (JC Company) manufactures SSMC connectors together with related cable assemblies, adapters and antenna products, supporting both standard and customized configurations.

Common Types and Characteristics

Type Mounting/Termination Coupling Typical Frequency Range Notes
SSMC Straight Plug/Jack Cable-to-cable, cable-to-board Snap-on DC–10 GHz General-purpose RF interconnection
SSMC Right Angle PCB mount Snap-on DC–8 GHz Used where board space or height is limited
SSMC Bulkhead/Panel Mount Chassis/panel Snap-on DC–8 GHz Front or rear panel feedthrough applications
SSMC End Launch (PCB) PCB edge mount Snap-on DC–10 GHz Direct board-edge signal transition

Comparison with Related Connector Series

Series Coupling Mechanism Relative Size Typical Frequency Range Typical Application
SSMC Snap-on Sub-miniature DC–10 GHz High-density board/module interconnection
SMA Threaded Miniature DC–18/26.5 GHz General RF, test and measurement
MCX Snap-on Micro DC–6 GHz Space-limited consumer/mobile devices
SMP Push-on (blind-mate) Sub-miniature DC–40 GHz Blind-mate board-to-board assemblies

Application Scenarios

  • RF and microwave test equipment requiring frequent, tool-free connect/disconnect cycles
  • Telecommunication base station modules and RF subsystems
  • High-density PCB layouts where SMA or TNC footprints do not fit
  • Instrumentation, avionics and defense-related RF signal routing
  • Internal cable assemblies within RF enclosures

Selection Points

Parameter Consideration
Frequency Range Confirm the operating frequency of the system falls within the connector's rated range
Impedance Match connector impedance (typically 50 ohms) with the cable and system impedance
Mounting Style Select straight, right angle, bulkhead, or PCB end-launch based on layout constraints
Cable Compatibility Verify cable type and diameter compatibility for stable termination
Mating Cycles Consider expected number of connect/disconnect cycles in the application
Environmental Requirements Check operating temperature range and any sealing or ruggedization needs

Frequently Asked Questions

Question Answer
What does SSMC stand for? SSMC refers to Sub-Sub-Miniature C, a snap-on style RF coaxial connector derived from the SMC series with a reduced footprint.
How does SSMC differ from SMC? SMC connectors use a threaded coupling nut, while SSMC connectors use a snap-on mechanism and a smaller physical size for higher-density layouts.
What is the standard impedance of SSMC connectors? SSMC connectors are typically designed for 50-ohm systems, consistent with most RF coaxial applications.
What frequency range do SSMC connectors support? Standard SSMC connectors generally cover DC up to approximately 10 GHz, depending on the specific design and cable used.
Can SSMC connectors be customized? Yes. Body plating, cable termination type, mounting configuration and dimensional details can be adjusted according to application requirements.
